+  draw
+  clone / merge
+  tick size
+  tick formatter
+  engineering notation
+  magnitude
+  rad, pixel, floor
+  drawText
+  measureText
+  getBestTextAlign

+
+
+Graph Architecture:
+===================
+
+Axis -
+  all series
+  orientation
+  ticks (major, minor)
+  scale (d2p, p2d, logarithmic)
+  notion of stacks
+
+Series -
+  per 'data'
+  notion of range (x, y, min, max)
+
+Graph -
+  DOM constructon
+  event attachment
+  options initialization
+  data range calculations
+  canvas spacing calculations
+  event normalization
+  draw methods
+  DOM cleanup
+  event cleanup
+
+
+Utilities:
+==========
+
+Color
+  build colors
+  parse textual color data
+  convert colors
+  clone colors
+
+Text
+  calculate text size
+  canvas size
+  html size
+
+Date
+  formatting
+  constants
+
+
+Spacing Calculation
+===================
+
+Flotr
+  calculate data
+  calculate margins
+
+Chart
+  calculate Data Ranges - Explicit or auto data minimum, maximums
+  calculate Data Range Extensions - By chart type, extend data range with needs of chart type (ie. stacked bars, stacked lines)
+  add Chart Padding - By chart type
+
+Text
+  use explicit margins
+  calculate label margins
+  calculate title margins
+
